When I went to Stern's Produce Market one time this summer, the nice young man taking my money observed that I had three bunches of green onions/scallions. He said, "You know, you can grow your own green onions from these plants after you use up the greens, don't you?"
No, I did not know that. When I get home from Stern's I always put the green onions in a glass of water to keep them happy until I am ready to use them. I have sometimes cut off a few of the greens and left the rest in the water. Amazingly, more greens begin to grow, so that one purchase of scallions gives a lot of nice "greens".
Well...after talking with the nice boy at Stern's, I used all the greens on my scallions then took the cut-off white bottoms with the roots on them upstairs to where we have a nice big planter in a south window. I planted them in the dirt and, in no time at all, lots of green came rushing up to the sky. I have cut them numerous times.
Sadly, in the last month-plus, I have not spent much time upstairs so the poor little creatures have not had any drinking water. I took this picture to guilt myself into taking better care of the scallions. I gave them a GREAT BIG drink and don't they look happy now!
This picture was taken after the watering.They are reaching for the sky again.
